- Member of the Turkish Ophthalmology Association; author of multiple SCI/SCI-E indexed publications on keratoplasty, keratoconus, and glaucoma.
Dr. Mehmet Orçun Akdemir is a member of the Turkish Ophthalmology Association. He has published 24 articles in international peer‑reviewed journals, many indexed in SCI/SCI‑E. He has 17 papers in national peer‑reviewed journals. He has given 5 presentations at international meetings.
His work centers on the cornea and anterior segment. Areas include keratoconus; DALK, PKP, and DSAEK; corneal biomechanics; and corneal cross‑linking. He also studies glaucoma surgery after keratoplasty, ocular surface disease and pseudoexfoliation, and neuro‑ophthalmology and retina. He contributed to 4 ophthalmology book translations. His studies compare DALK and PKP outcomes in keratoconus, analyze biomechanics after DALK, evaluate graft thickness after DSAEK, and compare trabeculectomy with the Ahmed valve in post‑PKP glaucoma.
